shower drainage

[tony89]

is it safe and possible to connect a shower waste to the bath waste trap,proposed shower trap to bath trap approx 2m.thanx

Depends on the route and gradient of the pipes. If the bath waste has to go out past the shower and the pipes are flattish then the shower tray will fill up. Ideally take the wastes out separately. Sometimes that's impractical so all you can do is take them away and down as far as possible and hope. You can get non-return valves for wastes but I would expect them to get fouled with hair etc on a shower waste.

thanxs,i think i will just have to re-route it(its just the hassle of it)

what about fitting a hepvo

I think it would work as a nrv but I wonder if it would restrict the flow from the shower. The hole you get, as far as I can remember, is only 25mm or so. Must check their website.
